GPT-6.1 Sol vs MiniMax M2.1
GPT-6.1 Sol leads MiniMax M2.1 on the Artificial Analysis Intelligence Index, 51.8 to 20.9, and MiniMax M2.1 costs 8.3x less per output token ($1.20 vs $10.00 per million). Updated October 22, 2026; 12 benchmarks have a result for both.
GPT-6.1 Sol or MiniMax M2.1: which to pick
Only GPT-6.1 Sol has a coding score, 82.4 on the Vibe Coding Index; MiniMax M2.1 has none, so the two cannot be ranked on coding.
Pick MiniMax M2.1 for output tokens 8.3x cheaper ($1.20 vs $10.00 per million).
